From 2001 Le Concert d'Astrée (= LCDA) and Emmanuelle Haïm received the support of the France Télécom Foundation. That same year, an exclusive recording contract was signed with Virgin Classics. In 2003 Le Concert d'Astrée received a 'Victoire' at the French Classical Music Awards as the Most Outstanding Ensemble of the Year.

Le Concert d'Astrée became ensemble-in-residence at Lille Opéra in 2004, for stage performances of G.F. Handel's Tamerlano, then, in autumn 2005, Monteverdi's Orfeo. It has also given concerts there, including G.F. Handel's oratorio Il Trionfo del Tempo e del Disinganno, Pergolesi's Stabat Mater and Mozart's C-minor Mass. It appears on other stages in France noted for opera (Opéra National du Rhin, Théâtre de Caen, Bordeaux Opéra, Théâtre du Châtelet and Théâtre des Champs-Élysées in Paris, etc.). Abroad, it has performed at the Concertgebouw in Amsterdam, the Barbican Centre in London, New York's Lincoln Center, the Konzerthaus in Vienna, and the Potsdam Festival, among many other important venues.
